Coins appear randomly. There is a maximum limit of coins that can spawn at one time, so you need to collect some before more will appear. Collecting them gives you a certan amount of money. You can spend your money on many useful items at the Shop. --Black Pixels make you lose a life. At the end of each level, five more Black Pixels will spawn randomly. ---Blue Pixels slow you down. They will appear at lvl 10. ---Green Pixels will give you an extra life.
---UPDATE 5/7/17--- You can now change your color in the Status menu. Yellow, Green, and Blue Pixel collecting is no longer glitchy ---UPDATE 6/20/16--- *The shop is no longer glitchy, but is still incomplete *Losing a life no longer gives the player a chance to glitch through the level *New black lines prevent the player from cheating *New maximum speed limit to prevent the player from glitching through levels *New status button displays lives, money, etc. *Straighter, smoother backgroud *Shop and Status buttons are out of the way (not limiting backdrop vision) *You can't cheat any more, so the cloud high score has been reset (I had the score anyways :P) The multiplyer (still) only works the first time you use it per game. I the game no longer works at a certain speed level.
